IMPROVEMENT IN SPINNING-FRAME.

TO ALL WHOM IT MAY couonnm Be it known that I, J. E. GROWEL'L, of Chelsea, in the county of Sufi'olk, and State of Massachusetts, have invented an Improved Spinning-Frame; and I do hereby declare that the following, taken in connection with the drawings which accompany and form -part oF this specification, is a description of uiy invention suificient to enable those skilled in'the art to practise it.

The invention relates generally to mechanism for spinning cotton and wool, and the object of the invention is to substitute a stationary spinning-frame for the ordinary mule or jack, and for the ordinarily arranged drawing-rolls thereof, by combining directly with each flyer,-or. sons to form part thereofia series of flyer-rolls fo-r'drawing out and taking upthe sliver while the flyer is imparting the twist thereto, the sliver passing directly from a sliver-spool upon which it is wound found through the noseof the flyer, and thence between the drawingl'olls in the fiyer-frzime. The invention consists, therefore, in combining with the fiyersof'a'spinnin'g machine drawing-rolls placed in the flyers, or so as to form" part of them, the flyers receiving the sliver directly from a spool or roll, and producing the-draw and twist threofwithout the interventionof intermediate drawing-rolls, thus greatly simplifying the spinning mechanism and producing a more uniformand finer yarn thpn can be spun by the ordinary mule or jack spinning. The invention further consists in the employment of an adjustable detaining bar located between the, fiycrs and the sliver-spool, and so constructed and arranged that the twist or the full degree of twist may be so regulated as to be prevented from extending back to the'delivery-rolls. The drawings "represent a spinning-frame embodying the invent-ion, and showing a full set of spindles-and flyers applied thereto-- I Figure 1 showing a front elevation, and

Figure 2am end elevation of the same.

a denotes the frame constructed to receive upon each side of it a spindle rail, 6, in which is a series of socket-bearinga c, for a series of spindles, cl. Each spindle extends up loosely through a traverse rail, e, and

iiyer raihf, and through a flyar, g, and the bobbins are placed upon the spindles in the ordinary manner. Each flyer g is journalled at top in a nose-plate, h, and as at bottom abuse-plate, z, secured upon the top of atnbular spindle or shaft, j. Each spindle, d, has upon it pulleyflc, from around which a band, Z, passes to'end around adrhin, m, and each fiyer-shaft j has upon it a'pulley, n, from around whichabaud passes to and around a. drum, afthe drums m and a being geared together through an intermediate gear and receiving motion from adrivingy pulley,p. Within each flyer there is fixed upon'or so as to rotate with its spindle d, a drawing-roll, g, which roll is corrugated or has gear-teeth out upon its surface that mesh into and drive two similar rolls r s journalierl in bearing-plates t at. in the fiyer g. Now the pulleys kand n are driven and rotate the spindle d and flyer g in the same direction, but the relation between the pulleys and drums is such that the spindle is rotated at a. greater speed than the flyer, thus producing a relative and increased rotation of the drawing-roll g and its connected rolls r 8. Over the top of the frame is a spool-holder, v, consisting of two crotched standards supporting the shafts bf a horizontal roll, 10, against the surface of which the sliver, wound upon two long spools, e, rests. Through suitable connections this roll receives motion from the driving-pulley p, and by contact turns the spools and allows the slivers to run therefrom. On each side of the frame a, at'its top, is a series of pairs ofdelivery rolls, a, one pair for each two spindles, and the lower rolls of each series are on a common shaft, 6, (supported in stationary bearings,) which reoeivesmotion from the driving shaft, and the upper rollsfivhose shafts turn in open bearings) rest upon and receive rotation from the lower rolls. These rolls may be fiuted', "and their office is to deliver or feed the slivers from the sliver-spool, the sliver passing froni" the spool between these rolls and thence to the noses of the respective fiyers'. Passing through the noseof each flyer, the sliver thence passes between the spindle-roll 'q and'the roll 1' on one .side of it, and thence partially around the roll or and between it and the roll a, from whence it passes through guiding eyes or hooks b to and is woundar'ouudthe bobbin 0' in the usual manner. Now, it will be rea'dily'seen that when the mechanism is in operation, and as the sliver is delivered by the rolls a, the twist will be imparted to the sliver by the rotation of the fiyer, and that by the increased speed of the spindle in the same direction the drawing-rolls g r s will simultaneously draw out the twisted sliver, the twisting and drawing taking place simultaneously over the same portion of the sliver, (or that portion between the bobbin and the delivery rolla) thus not only producing a uniform twisting and draw ing action upon the sliver ,-but, from the manner of doing this, enabling the sliver to be much more finely spun and safely attenuated than by 'the old methods of spinning. To prevent the full degree of twist from extending hack to the delivery-rolls, a detainor-bar, (Z, is interpesedtbetween the delivery-rolls and the nose-plate, which bar may be provided with notches, through which the slivers run; This bar is made adjustable, and so that it may be set in such position as to produce such bend or angle in the'sliver between the flyer-nose and the delivery-rolls, as may bc nccessary. The impingement of the sliver upon the edge 0? this bar keeps-most 0f the twist below the bar, allowingenly such degree of the twist to extend above the bar to the delivery-rolls as SllZl-ll be in accordance with the quality of the slivers being spun or the kind of yarn to be produced. This allows such degree df strain upon the sliver as it will admit of nearest the delivery-rolls, which strain is increased as the twist increases below the detainerbar. By fixing the bar in a higher ,or lower position the degree of twist extending above the bar may be increased or diminished, as circumstances may require. The spindle drum m is geared to and driven by the driving-shaft of the dyer-drum o by gears f on the respective drumshafts and an intermediate gear, g. The spindle-drum gear a and the intermediate gearg are made removable, t

and may. be replaced by others of different diameters so as to produce changes between the relative speed of the spindles (and their drawing rolls) and the flyers. It, with a given delivery, we wish to have greater twist inthe yarn, a larger gear is placed on the spindle-drum shaft so as to increase the-revolutions of the spindle and its drawing-rolls, and to obtain less twist the lower gear is replaced by a smaller one. If we 'wish to deliver the sliver faster from the sliver-spool we place a-large gear on the shaft, which drives the gear on the delivery-roll, replacing the gear on the delivery-roll by a corresponding smaller one. As the mechanism for producing the rise and fall of the bobbins (to effect the even laying of the yarn upon I the same) and. for lowering the spindle rail for removaland replaeement'of bobbins, and the other mechanism, apart from that dcserihedfor drawing and twisting the sliver, are not of the essence of this invention, it need not be particularly described.

I claim, in combination with the fiyers of a spinning-frame, drawin -rollsarranged within the flycrs, when one of said rolls in each flyer is directly open the spindle and meshes into and drives the others, substantially as shown and described.

I also claim combining with the drawingd'olls and the'fiyers of a spinning-frame a detainer-bar interposed between the drawing and twisting mechanism and the delivery-rolls, substantially as and for the purpose described.
